i PROGRAM ATTACHIMENT FOR CLOCKS.

v Application filed February as, 190s. A`serial No. 418,339.

To all whom 'it may concern:

citizen of the United States, residing at Princeton, in the county ofGibson and State.

of Indiana, have invented certain new and useful Improvements in ProgramAttachments for Clocks; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to program attachments for clocks. y

The object of the invention is `to provide an attachment of thischaracter whereby oneor more bells may be rung or other signalsA soundedwhen arranged in the same or dif-' ferent locations.

A further object of the invention is tov provide a simple and efficientapparatus ofthis character adapted to be applied to the hour-shaft andstriking-mechanism of an ordinary striking clock to make and break oneor more electric circuits, whereby one or more bells in each "of saidcircuits are rung at any desired time. l

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be described and par-l ticularly pointed out vin the appendedclaims.

In the accompanying drawings, Figure 1 is a front view of a clockshowing a diagrammatic arrangement of the invention connected thereto;Fig. 2 is a rear view of the same; Fig. 3 is a front view of the clockworks with parts broken away to more clearly disclose the connection ofthe invention thereto; Fig. 4 is a side view of the same, with partsbroken away; Fig. 5 is a plan view of the hour dial; Fig. 6 is a detailsectional view of the same, showing the arrangement of the contactbrushes for engaging the contact pins thereon; Fig-7 is a detailperspective view of one of the contact pins of the hour dial; and Fig. 8is a sectional view of the same.

This invention is adapted to be applied to the worksof aiiordinarystriking clock and consists, primarily, of two dials, which, forconvenience of reference, I will term minute and hour dials. The minutedial, 1, consists of a circular disk of metal or other suitablematerial, on the outer side of which, near its edge, the same is dividedinto sixty minute divisions, and opposite certain of Specification ofLetters Patent.

pins being shown in the present instance as arranged opposite each fiveminute division. These pins, however, may be arranged at any of thedivisions on the dial.

said divisions are arranged trip pins, 2, said Be it known that I,JULIUS W. HANSEN, a`

The dial, 1 is preferably arranged on the rear side of the clock works,and is securedv to the minute hand of the shaft of the clock, said shaftbeing extended beyond the rear side of the works to receive said dial,the latter being rigidly connected to said projecting end of the shaftby set-screws, or other suitable fastening devices.

rIhe trip pins, 2, are adaptedto be brought into successive engagementwith a lifting rod, 4, which is similar to and corresponds with theordinary lifting rod of the striking The rod, 4, is connected to atripping shaft, 5, which is pivotally mounted in the frame of the clockwork and is here shown as being bent over the upper edge of said frameand thence downwardly in rear of the same in position to be engaged bythe pins, Q. The shaft, 5, has secured thereto, near its opposite end, atrip rod, 6, the lower end of which is adapted to engage a secondtrip'rod, 7, which is fixed to and projects from a second trip shaft, 8,to which is also secured a stop arm, Q the outer right-angularly bentend of which is normally in the path of movement of a stop pin, 1 0,which projects laterally from one of the gears, 12, of the strikingtrain, thereby holding the striking mechanism against movement untilreleased by the upward movement of the stop arm, 9, which movement iseffected through the engagement of the trip pins, 2, with the liftingrod, 4, and the parts operated thereby, as hereinbefore described. Tothe trip shaft, 8, is also secured a contact rod, 13, the lower end ofwhich is bent at right-angles and is adapted to drop into engagementwith a notch, 14, formed in the commutator disk, 15, which is fixedlymounted on the shaft of one of the gears of the striking train torevolve therewith. When the trip shaft, 8, is turned through themechanism operated by the trip pins, 2, to start the striking mechanism,the contact rod, 13, will be lifted out of engagement-with the notch,14, and will rest on and be held up by the outer edge or periphery ofthe commutator disk while the latter is revolving and until the notch,14, is again brought opposite .to the right-angularly bent end. of therod, at whichtime said rod will again drop into the notch, and at whichtime, the stop arm, 9, Will also drop into the path of movement of andbe engaged by the stop pin, 10, on the gear 12, of the striking train,thus stopping the movement of. the latter. When the contact rod, 13, hasbeen lifted in the manner hereinbeforedescribed, the same will bebrought into engagement with the contact brush, 16, which is arranged inthe path of upward movement of said rod, and is secured to the clockframe or casing in any suitable manner. To the brush, 16, is connectedone end of an electric Contact Wire, 17, which extends to the batteries,1S, and forms part of an electric circuit. During the time the contactrod is held up by its engagement with the periphery of the commutatordisk, said rod is held in engagement with the contact brush, 6, thuscompleting the circuit at this end of the Wire. This engagement of theContact rod with the contact brush occurs every five minues or each timeone of the trip pins, 2, comes into engagement with the lifting rod, 4,as hereinbefore described.

The methodV of completing the entire circuit to ring one or more bellsat the desired time will now be described: rThe completing of the entirecircuit is accomplished by means of the hour-dial, 19, Which consists ofa circular disk formed of metal having suitable conducting qualities,said disk being firmly secured to the tubular hour hand of the shaft ofthe Works by means of setscrews or other suitable fastening devices. Theouter face of the dial is provided With twelve hour divisions, each ofWhich is subdivided into twelve tive minute divisions, or, if desired,the hour divisions may be subdivided into minute divisions. On the hourdial is arranged one or more series of adjustable contact pins, which,in the present instance, are shown as consisting of an outer series ofpins, 20, and two inner series of pins, 21, 22. The pins, 20, of theouter series are adapted to be brought into engagement with a contactbrush, 23, While the inner series, 21, 22, are adapted to be broughtinto engagement With contact brushes, 24: and 25, said brushes beingconnected to electric con` ducting Wires, 26, 27 and 28, which are inturn connected to one or more electric bells, 29, which are arranged inthe circuit of the conducting Wire, 17, from the brush, 16, which makesconnection with the Contact rod operated by the minute dial so that whenone of the contact pins in any or all of the series comes intoengagement with the contact brushes, the entire circuit will becompleted, through the dial, 19, and the works of the clock, therebyringing one or all of the bells in the circuit.

The contact pins of the hour-dial may loe adjust-ably secured thereto inany suitable manner, but are here shown and are prefercomme ably securedin a series of concentric segmental slots, 30, formed in the dial, saidpins consisting ot a base plate, 31, which is adapted to be engaged withthe underside of the dial, and adjustably secured 'thereto by set-screws31, which are passed through said slots and engage threaded apertures insaid base plates. The plates, 31, have one end bent upwardly andinwardly to form a hookshaped flange, 32, Which is adapted to be engagedwith the edges of the slots or vwith the outer edge of the dial asshown.

Atthe outer end of the base plate, 3l, adjacent to the flange, 32, areformed upwardly projecting contact fingers, 33, which project outwardlybeyond the face of the dial in position to engage their respectivebrushes when brought opposite thereto by the movement of the dial. Thefingers, 33, on some of the pins are arranged on one side of the fiange,32, While on other pins said fingers are arranged on the opposite sideol the fiange so that when more than one of the pins are arranged in aseries, said fingers may be broughtcloser together, thus making itpossible to complete the electrical circuit at Very short intervals.There may be any number of pins arranged in each of the i series, sothat the bell or bells controlled by each series may be sounded asfrequently as desired. ln the present instance, the slots for adjustablyholding the pins on the dial are arranged between the hours ot eight andtwelve an one and tour, thus making it pos- `sible to sound the bells atany time between or during these hours. It is obvious, however, that theslots may be formed in the dial to permit the setting of the pins toring the bells at any hour or fraction thereof.

1n the operation of the device, assuming that it is desired to sound thebell or bells controlled by the outer series of contact pins at eightoclock, one of the pins in the outer series or slot of the dial will beset opposite to the division eight on the dial. As the hour of eightapproaches, the pin opposite this division will be brought intoengagement With the brush, 23, thus completing the circuit controlledthereby, the opposite end of the circuit being completed through thebrush, 16, by its cont-act with the rod, 13, which is engaged therewithevery five min- 'utes through the mechanism operated by the trip pins onthe minute dial. In the same manner, one or more of the pins on thehourdial may be adjusted to the hour when it is desired to ring thebells in the other series, thus making it possible to ring the bells ofall the series at the same time, or at different times. 1t will beunderstood that the bells of the different series may be arranged indifferent rooms or that several bells may be arranged 'm each series,and located in different rooms or places where it is desired to soundthe signals.
